* QEglFSKmsGbmScreen::framebufferForBufferObject: release() at the correct timeMarc Mutz2024-04-181-2/+3
| | | | | | | | | | | | | | | It's the gbm_bo_get_user_data() function that takes ownership of the FrameBuffer object, not the caller of the function, so release() into gbm_bo_set_user_data() not into the return. This threw Coverity off, which complained about a leak of the return value in the caller.

* eglfs_kms: Prevent drm errors with more than one window during the screen's ↵Laszlo Agocs2022-12-121-1/+10
| | | | | | | | | | | | | | | | | | | | | | lifetime The QML Live Preview tool exercises the problematic case of having a QQuickWindow, then closing it, then showing another, then destroying that, ..., and so on. It seems that the eglfs_kms backend does not handle this gracefully: if there was a page flip issued for a window that is then closed, the new window will result in drm errors (like -22 EINVAL) because the logic gets confused due to holding on to surface buffers from the old window. To remedy this, make sure the same cleanup is performed on a failing atomic commit as it is done on the non-atomic code path. In addition, reset more things in resetSurface().

This should not be needed and is discouraged (will certainly cause deadlocks in multiscreen setups + QQ threaded render loop on certain embedded systems), but it seems necessary to provide a way to revert back to the old way of functioning as there are reports about problems with screen cloning when the dedicated event reading thread is used.

* Add a way to declare _exported_ logging categoriesGiuseppe D'Angelo2022-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a library declares a logging category that needs to be used by clients (e.g. via inline methods, macros, etc.), then the logging category function generated by Q_DECLARE_LOGGING_CATEGORY has to be exported. We've seen this problem with Q_NAMESPACE, Q_GADGET, etc.: these macros also declare functions or objects that in some cases need to be exported. And precisely like Q_NAMESPACE, Q_GADGET, etc., people end up relying on the implementation details of Q_DECLARE_LOGGING_CATEGORY (specifically, what does it expand to) in order to place the export directives in the right place. Introduce a more robust solution and apply it around qtbase. Cleanup some minor code as a drive-by (remove `extern` and useless semicolons). [ChangeLog][QtCore][QLoggingCategory] Added the Q_DECLARE_EXPORTED_LOGGING_CATEGORY macro, in order to allow dynamic libraries to declare a logging category that can be then used by client code.

But in CMake, the implications of this are that public usage requirements should then be propagated to consumers. We don't expect any consumers, since a plugin is created as a MODULE library in CMake, so for Windows we don't even have an import library to link with. The only exception to this is for static builds where plugins are created as STATIC libraries instead, but only in certain controlled situations do we then link to plugins. Even then, usage requirements are not expected to propagate to the consumers, so these relationships should always be specified as private.

| | | | | | | | | | | | | | | | | | | | A protected context is required to allow the GPU to operate on protected resources, including protected surfaces and protected EGLImages. For example, GPU can post-process on protected content like DRM protected content so that complex, nonlinear video effects or mapping onto textures can be used. The surface format option may be relevant for DirectX and Vulkan in the future: https://microsoft.github.io/DirectX-Specs/d3d/ProtectedResources.html https://www.khronos.org/registry/vulkan/specs/1.1-khr-extensions/html/chap12.html#memory-protected-memory Change-Id: I2d155f0e68b830276690b4833b22a2bc452cdcad Reviewed-by: Elvis Lee <kwangwoong.lee@lge.com> Reviewed-by: Eskil Abrahamsen Blomfeldt <eskil.abrahamsen-blomfeldt@qt.io>
* Long live VK_KHR_display platform plugin!Laszlo Agocs2021-02-082-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Experiment with this once again, this time in a more forward looking manner: move the code previously placed into eglfs's eglfs_viv backend into its own plugin. Move our attention to devices like the Raspberry Pi 4, where VK_KHR_display has recently been introduced to the Mesa v3dv backend. This is not in Mesa 20.3.3, the latest release at the time of writing, but is available and functional when building master. This serves as the reference system for testing the plugin, because it looks like a fairly robust implementation. The sole thing the plugin enables at the moment is creating a QVulkanInstance and a QWindow with surfaceType VulkanSurface. This is sufficient to run plain QWindow+QRhi (with QRhi::Vulkan), Qt Quick, and Qt Quick 3D (with QSG_RHI_BACKEND=vulkan) applications. One display and mode is chosen, by default the first in the enumeration lists reported by the Vulkan extension. This can be overridden with QT_VK_DISPLAY_INDEX and QT_VK_MODE_INDEX (modeled after QT_VK_PHYSICAL_DEVICE_INDEX). The indices can be determined based on the logs printed to the debug output. Changing the mode seems to be working nicely with v3dv. Multiple screen setups, where there would be more than one VkDisplayKHR enumerated, have not been tested yet. Regardless, multiple screens (reporting more than one QScreen, with a different QWindow on each, eglfs style) are not currently supported. This may be improved later (while keeping in mind that VK_KHR_display does not have a fully-featured output management API). Multiple (non-fullscreen) windows and especially raster windows (QWidget) are not and will not be supported. Our single QWindow is always forced to fullscreen. When it comes to input, the level of support should match linuxfb and eglfs. Note that while mouse input is fully functional, there is no mouse cursor. (and this is unlikely to be implemented) [ChangeLog][Platform Specific Changes][Embedded Linux] Introduced a vkkhrdisplay platform plugin to run Vulkan-based applications in fullscreen, without a windowing system, on systems where VK_KHR_display and VK_KHR_display_swapchain are supported by the Vulkan implementation.
